TRAIN FAN SYSTEM.

Specification of Letters Patent.

Patented Dec. 1, 1908.

the statute will be described with special reference to train fan systems, it being understood however, that the invention 1S not limited thereto, but that the invention is so steam connection 6 of the pump a and described in order to distinctly and definitely set forth one embodiment thereof.

In the accompanying drawing I have shown in Figure I a suflicient number of parts of a railway train to illustrate one embodiment of my invention. In Fig. II, I have shown the details of the arrangement of the auxiliary reservoir upon each car.

In the drawing A represents a locomotive,

' B the tender, and C the first car of the train of which there may be several.

Mounted upon the locomotive is a suitable air-pump a receiving steam from 'the locomotive boiler through the connection b and preferably .exhausting into the stack through the exhaust 0. Leading from the air-cylinder of the compression pump a is a train line (Z, which communicates through suitable couplin s and flexible connectione with a coil ofipipingf herein shown as located in the tender B. Carried upon the tender is a reservoir g having a fluid seal 8 beneath which the delivery pipe 71 of the coil ,1 dips.

Leading from the upper portion of the reservoir g is a continuous train-pipe d which leads to auxiliary reservoirs it having check-valves 70 shown beneath the floor of thecar, carried by-the respective cars.

The reservoirs g and h are preferably prothe respective auxiliary reservoirs. h are 'pipes' l in each car which lead to pneumatic fans carried upon the "car.

Asuitable regulator o is interposed in the connected by pipe with the train pipe (1.

The function of this regulator is to control by means of the air-pressure the admission of steam to the air compressor a so that when the air-pressure falls in thesystem the regulate): Q. will operate to opens} valve to admit steam tothe air-compressor so that the pressure will be pumped up.

The air from the,air-compressor passin through the. train pipe d traverses the coi or condenser f and is thereby cooled and deposits moisture inthe condenser f and the reservoir g. The air passes through the water-seal in the'reservoir g and is thereby scoured or cleansed. The air passes from the reservoir 9' to the auxiliary reservoirs h in each car and thence is supplied to the fans m in the cars. The reservoir 5/ serves to trap the moisture in a very eiiicient man ner and the air passes to the auxiliary reservoirs clean and dry, it being quite essential that the exhaust shall be clean and dry, otherwise the air discharged into the cars by the fans will scatter dirt and moisture and thereby ruin the furnishings. v

The, heat given oil bythe air when it is cooled in the tender is useful in that it tends to heat the teed-water of the locomotive.

It will he understood that the location of the various parts is not essential.

Having described my invention. what I claim and desire to secure by Letters Pat cnt 1s:

1. In a train ventilating system, in combination, an air compressor carried by the locomotive and driven by steam from the boiler, a coil located in the .tender' of the locomotive through which said compressed air passes adapted for condensing moisture therefrom, 'means carried by said tender for scouring the compressed air when the same has been delivered from said condensing coil, said scouring means being also adapted to receive the drippings from said condensing coil, a storage tank located upon each 'car of the train, a train pipe leading from.

said scouring means and communicating with each of said tanks, a pneumatically driven fan carried by each of said cars, and a conducting conduit leading from each of said storage tanks to one of said fans.

2. In a train ventilating system, in combination an air compressor carried by the locomotive and driven by steam from the boiler, a condensing coil carried by the tender of the locomotive and communicat- -ing with'said compressor whereby the compressed air may have the moisture condensed therefrom, scouring means carried by said tender and-communicatmg with said con-
